Answer #1
We have given that,
Sample mean =85.077
Sample standard deviation =16.444
Sample size =13
Level of significance=0.1
Degree of freedom =12
t critical value is (by using t table)=1.7823
Confidence interval formula is
=(76.948, 93.206)
Lower confidence limit=77.0
Upper confidence limit= 93.2
